Topic: boil off - extract (Read 866 times)

So I am going to be attempting a full boil this weekend. I am still brewing extract but will be making a 10 gallon batch. I would like to try my hand at a full boil but I have a quick question.

Based on everything I have searched people say it depends, but I was hoping someone could give me a good average number of how much water I should start with if I was to doing a 10 gallon batch. 11 gallons? 12 gallons?

If you want to dial it in for your system before brew day throw a few gallons into the kettle, measure at the beginning, and boil it for half a hour, and measure it at the end. That'll let you estimate how much you'll boil off on brew day.

With extract unless you are adding it all at the start of the boil you're volume will change when you add it in.

I do most of my extract as a late addition, so I would need to know my boil off rate as well as estimate the displacement/volume addition of the late add extract. I suppose it could be figured out, but...

good point. I think i am going to add all of the extract at the beginning. So the volume would be what...roughly 2 gallons (guessing) for a 10 gallon batch. expecting 1-2 gallon boil off. I will try it out this week prior to brew day.
